Driving Use Cases Easy deployment of geospatial tools

Driving example Multi-scale and multi-disciplinary data and modeling

for addressing hydrologic and ag economic issues

Overarching goal:

Making it easy for scientists to share geospatial data and tools

Reach broader user community Anyone can create an online app and share Anyone can share geospatial data

Outcome

The rapid tool development library RAPPTURE will support geo-referenced data objects (maps, images, etc) Easy way to share geospatial data, both in raw data, and

visually and interactively Easy way to share interactive tools that uses, and produces

geospatial data

Tool builder that supports geospatial data to further lower the barrier of creating interactive online tools

Service interfaces to upload and share geospatial and other types of data in HUBzero

Service interfaces to link tools and data

Geospatial capabilities as part of core HUBzero open source release

Funding A National Science Foundation grant

Data Infrastructure Building Blocks (DIBBs) program

GABBs: 1 of 4 implementation awards in 2013

$4.5M, 4 years (10/2013 – 9/2017)

Collaboration with other DIBBs and DataNet awards
